If anyone enjoys INCAL, I highly recommend MetaBarons which is even more Dune inspired and the storyline gets insane, but wondrously done.

And now we must duel to the death!
I personally think science fiction goes from "hard" SF to "soft" SF to what I like to call "mushroom" SF (or simply "mushroom fiction" because there is no science in it). Jodorowsky and Moebius are the people who made me come up with the latter terms years ago (they were actually high on mushrooms when they wrote some of their stuff).
I absolutely agree that "Mushroom SF" is a good description of Jodorowsky, Moebius and much of Heavy Metal / Metal Hurlant. It's space fantasy with little, if any, care about the science part of science fiction.
I won't be surprised if David Lynch chomps on shrooms when doing scripts and storyboards for any of his films.
Jodorowsky's vision is super-trippy, and probably would have looked more like 5th Element (one of the most "mushroomy" films I know, and which stole a lot from Jodorowsky).
Visually, Valerian and City of a Thousand Planets (also by Luc Besson of 5th Element) shares elements of that "trippy scifi".
However, when reading Dune, I envisioned something far more "trippy" and fantastical than Asimov's Foundation whose setting feels far more concrete.
The trailer shows neither. It's generic modern movie scifi, only out of fear of daring to present a new vision. Even Guardians of the Galaxy and Thor: Ragnorak had the balls to step outside the lines.
At this point, I doubt we're going to get a truly original scifi vision out of Hollywood. Maybe a Russian, Brazilian or Korean movie.
